Problems solved by technology

In addition, carbon dioxide stored in seawater is likely to escape from seawater and be released into the atmosphere when encountering temperature and pressure fluctuations or changes in ocean currents, which will cause results that run counter to carbon dioxide sequestration

Embodiment 1

[0028] with CO 2 The gas is a foam geopolymer filled with gas, and the solid powder is slag micropowder produced by Xuzhou Chengyi Cement Plant and secondary fly ash of Xuzhou Maocun Thermal Power Plant. The mass percent composition of the solid powder is: 50% of slag fine powder and 50% of fly ash fine powder. The liquid-solid ratio is 0.5, and the amount of water glass (as Na 2 O meter) accounts for 4% of solid powder weight, and foaming agent consumption accounts for 1% of solid powder weight.

[0029] The preparation method is as follows:

[0030] (1) Composite powder material preparation: The slag micropowder and solid waste slag powder are weighed and proportioned, and mixed evenly to obtain a composite powder material.

[0031] (2) Foam preparation: The mass of water and foaming agent is prepared at a ratio of 30:1 to prepare a foaming liquid, and then the CO 2 The gas is passed into the foaming machine to prepare foam.

[0032] (3) Preparation of geopolymer slurry...

Embodiment 2

[0035] Basically the same as Example 1, the difference is: the mass percent composition of solid powder: slag fine powder 100%. The liquid-solid ratio is 0.6, and the amount of water glass (as Na 2 O meter) accounts for 5% of solid powder weight, and foaming agent consumption accounts for 2% of solid powder weight. In foam preparation, the mass ratio of water to blowing agent is 50:1.

Embodiment 3

[0037] It is basically the same as Example 1, except that the mass percentage of solid powder is composed of 20% of slag micropowder and 80% of solid waste slag micropowder. The liquid-solid ratio is 0.3, and the amount of water glass (as Na 2 O) accounts for 3% of the weight of the solid powder, and the amount of blowing agent accounts for 0.1% of the weight of the solid powder. In foam preparation, the mass ratio of water to blowing agent is 20:1.

Abstract

The invention discloses a foam geopolymer taking CO2 as filling gas. The foam geopolymer takes slag micropowder and other waste solid micropowder as main raw materials, takes water glass as an exciting agent and takes CO2 as the foam filling gas, wherein solid powder comprises the following components by mass percentage: 20-100% of slag micropowder and 0-80% of waste solid micropowder; a liquid-to-solid ratio is 0.3-0.6; the dosage of the water glass accounts for 3-5% of the mass of the solid powder; the dosage of a foaming agent accounts for 0.1-2% of the mass of the solid powder. According to the geopolymer, the strength of the geopolymer can be improved by absorbing CO2 by a carbonization reaction; the foam geopolymer can realize transient sealing of CO2 and permanent solidification of CO2 after slow overflow and gradual soil absorption; effective unification of utilization, sealing and solidification of CO2 is achieved; the foam geopolymer is a stable and long-time carbon sequestration manner.

Description

technical field [0001] The present invention relates to a kind of polymer foam, in particular a kind of CO 2 The gas is a foamed geopolymer filled with gas, which belongs to the sequestration and solidification of CO 2 Derivatives for the purpose, and a preparation method thereof is disclosed at the same time. Background technique [0002] Global warming has been highly valued by countries all over the world, and its hazards have deeply affected people's lives, such as melting glaciers, rising sea levels, flooded islands, extinction of animals and plants, ecological imbalance, frequent natural disasters, and the spread of infectious diseases; carbon dioxide (CO 2 ) emissions have been recognized by countries all over the world as the most important man-made factor of global warming. Therefore, various international agencies, climate organizations and governments are looking for ways to reduce CO2 emissions. 2 the fastest and most efficient way. Although countries respon...
